Description
It is an AC-DC 110V to 1.25V-12V LM317 Adjustable Step Down Power Supply Buck Voltage Converter LED Display DIY Kit. It can output stable voltage. Users can change output by operating a potentiometer. It also can be used as a signal generator or logic circuit or buzzer alarm circuit.
Note:
1>. It is a DIY kit so that needs finish install by the user.
2>. Its max output power is 2.5W.
3>. It can not be used as a charger.
Since the output current is not large, it can only supply power to the small current circuit.
